摘要： Techniques for reducing the time required for erasing specific data recorded on a tape medium. A specific group of records is erased without preliminarily locating the erasure end position. This is carried out by simultaneously utilizing three heads, that is, two read heads and one write head, to detect the erasure end position during data erasure. Various embodiments are applicable to tape media as well as other storage media. Various embodiments are not only applicable as a file system cooperating as a combination of hardware (H/W) and software (S/W), but also applicable in systems, such as databases, that directly use storage without an intermediary file system.

摘要： Described are embodiments of an invention for customizing the range of acceptable write conditions to a tape of a tape cartridge that contracts or expands laterally based on environmental conditions. The tape drive utilizes servo information to determine if the tape has expanded or contracted from the nominal dimension and to determine the magnitude of the expansion or contraction. In the case of expansion, the magnitude of the determined expansion and the stored maximum amount of contraction must be below a predetermined threshold value to allow a write. In the case of contraction, the magnitude of the determined contraction and the stored magnitude of expansion must be below the same predetermined threshold value to allow a write. If the determined magnitude of contraction or expansion is greater than the stored magnitude of contraction or expansion, respectively, then the new extreme is stored.
摘要翻译：描述了根据本发明的实施例，用于根据环境条件将可接受的写入条件的范围定制到横带收缩或扩展的带盒的带。磁带驱动器利用伺服信息来确定磁带是否从标称尺寸扩展或缩小，并确定扩展或收缩的大小。在膨胀的情况下，确定的膨胀的幅度和存储的最大收缩量必须低于预定的阈值以允许写入。在收缩的情况下，确定的收缩的幅度和所存储的扩展幅度必须低于相同的预定阈值以允许写入。如果确定的收缩或膨胀的大小分别大于收集或膨胀的存储量，则存储新的极限。

摘要： The subject innovation relates to systems and/or methodologies for using randomly positioned electromagnetic scatterers deposited into a predetermined region of an optical storage medium (e.g., Blue Ray DVD, HD DVD, CD, etc.) as a distinct three dimensional (3D) hard-to-copy digital rights management feature. A scatterers' topology is scanned using a matrix of antennas that sense the scatterers' electromagnetic response as the optical disc revolves at near-constant angular speed. The response, f, called an RF fingerprint, is then concatenated with an arbitrary text, t, that defines the digital rights management information imposed by the disk publisher.

摘要： Write commands through a read/write head are regulated in response to head fly height. The head fly height is determined, and the rate at which the write command is carried out is regulated in response to the determined fly height. The rate may be regulated by inserting write inhibit gaps between writing data segments of the write command so as to allow the head to cool and, thereby, control fly height.
